Abstract

A signalling device comprises means for storing electrical energy, e.g. a battery (41) which are connected to signalling means such as one or more LEDs (48). Control means (45) are provided to prevent actuation of the LED (48) so long as current is supplied and to activate the LED (48) if that current falls below a threshold. For many applications, the device preferably includes one or more solar cells to generate current to the control means (45) and hence to render the device sensitive to the presence or absence of ambient light.
